UBV photometry of EZ Hya. The beginning of mass-transfer detected?

Photoelectric observations of the sort period eclipsing binary EZ Hya are presented. Precise light curves were constructed an eight times of minimum light were derived. A detailed period study shows that this system started decreasing its period in 1970. This may be interpreted as the beginning of a...
